GERARD MEIJSSEN encouraged us and taught us what was needed to make a Wikipedia. See Gerard's blog...

STEPHEN E. SLEVINSKI JR. developed the software and encoding necessary for writing sign languages in vertical columns in SignWriting on the web and on Wikipedias.

YAIR RAND developed the JavaScript Keyboard making it possible to type SignWriting directly in text fields on the web.

MOHAMED ALI BALTI ("Dali") founded the Tunisian Sign Language Wikipedia, contributing three articles in 2016. Dali also wrote an Instruction Manual teaching other writers how to write an article in the Sign Language Wikipedias, using SignPuddle Online and the RAND JavaScript Keyboard.

ADAM FROST founded the American Sign Language Wikipedia. As the Deaf ASL Editor, Adam translated the Wikipedia menus from English to ASL using "Translate Wiki". Adam contributed the first ASL article in the ASL Wikipedia: "Charles-Michel de l'Épée", and he continues to edit articles and gives teaching and tech support to new ASL writers.
